Abstract:
Several works have shown the link between congestion control in communication networks and feedback control system. This paper is an extended version of [1] and proposes the design of an Active Queue Management (AQM) that ensures the congestion control stability. To this end, tools from control theory, and especially in a time delay systems framework, are considered. We aim at stabilizing the Transmission Control Protocol (TCP) as well as the queue length of the congested router. Furthermore, the control mechanism is then completed to deal with the stability issue under some non-responsive crossing traffic modeled as perturbation. Finally, a numerical example and simulations via the Network Simulator NS support our study.
